According to Dan at Canada Ammo they have a couple hundred DA 50 single shot 50 cal uppers in the works.
We have received several inquiries of late as to whether we would entertain re-introducing the NR lowers that we manufactured a few years back that were then mated to the DA50 uppers.
The question I need the answer to is, is there enough demand for these to warrant the purchase of another CNC milling machine and the hiring of another machinist to run them?
We have the entire shop fully engaged at this time and likely for the next 18 months machining Modern Sporter receivers and I will not hinder that production in any way.
As near as we can determine cost will be in the $850.00 area, but if there is enough interest I will take the time to figure out to the nickle the final cost, but like everything, yes it will increase from years ago. This will include the modifications required to the uppers to allow it to mate to the NR lower, just as before.
These mods are irreversible so the upper will never mate to an AR15 lower again.
